It's all a bit more of a spectrum.
There is serious money behind the chemical mental-distress-as-an-illness interpretation. If it's a medical problem then you need a medical solution. Anti-depressants anyone? They are being taken in such vast quantities they are starting to poison the water. [1]

also this conversation is about true clinical depression and the difference between it and just feeling sad; it's not about some conspiracy theory of how every doctor wants us to be on meds or the fact that flushing medication down the toilet is poising our water supply.
please stay on topic if you want to continue the converation
Who gets to decide what is "feeling sad" with a cause and what is idiopathic "chemical malfunction". Care to offer any references? Objective diagnostics?
I included the bit about antidepressants to caution swallowing the prevailing medical model hook line and sinker with out pause for thought as to it's assumptions. Pretty sure that's on topic.
So... there may not actually be a huge difference in feeling sad about trauma and chemical problems. Not all chemical problems are genetic.
You are promoting a stigmatising, out of date, notion of mental illness which is based on ignorance. You are suggesting (whether you know it or not) that some depression is "real" (and based on a chemical imbalance) and some depression is not real (and is not based on a chemical imbalance).
This is unhelpful, and potentially dangerous.
It leads people to think that medication is the only way to treat depression. Medication is not the only way to treat depression; medication alone is unlikely to be much use for long term resilience.
The "Chemical imbalance" model is too simple and has too many flaws to be much use.
